  • Patent number: 8366700
    Abstract: Visceral fat may be removed from a subject using a cannula that has an interior cavity and an orifice configured to permit material to enter the cavity. This is accomplished by generating a negative pressure in the cavity so that a portion of the tissue is drawn into the orifice. Fluid is then delivered in pulses, via a conduit, so that the fluid exits the conduit within the cavity and impinges against the portion of the tissue that was drawn into the orifice. The fluid is delivered at a pressure and temperature that causes the visceral fat to soften, liquefy, or gellify, without damaging the subject's internal organs that are in the vicinity of the visceral fat. The visceral fat that has been softened, liquefied, or gellified is then suctioned away.

  • Patent number: 7762997
    Abstract: A unique construction of this douche ensures that the incoming and outgoing streams of cleansing liquid do not mix inside the device. Thus it provides a superior cleansing of the vagina. The device has two parts: an inner core and an outer casing, which so snap fit together that create two isolated spaces inside the device securing no leakage between them. The parts are easily separable for cleaning purposes. The base of the device is round so, when placed against the entrance of the vagina, it acts as a plug. The base has two pipe connectors for a cleansing liquid, an inlet and an outlet, and these are interchangeable. A stream of liquid passing through the device smoothes out folds of the vagina, covering its entire surface, and thus ensures Improved hygiene and therapy. This douching device simultaneously provides vaginal hydromassage, which can be enhanced by manually compressing the outlet.

  • Patent number: 6942635
    Abstract: Disclosed are various embodiments of a hemo-dialysis catheter in which the aspirating port at the end of the aspirating tube is distal of the infusion port or ports at the end of the infusion lumen. The infusion port or ports are arranged circumferentially so that the infused filtered blood is a substantially 360° jet of fluid with a substantial radial component. This jet of fluid serves to abrade the occlusive material that is composed of fibrin and other components that grows down along the outer wall of the catheter that would otherwise tend to block off the ports. Stopping occlusion growth at the zone of the infusion ports prevents further growth distally to the aspirating port and protects the aspirating port from being blocked by the growth of occlusion.

  • Patent number: 6485452
    Abstract: A medical suction and irrigation apparatus includes a suction/irrigation tip removably connected to a conventional suction/irrigation handpiece. Suction is provided through a suction tube which has a bypass conduit in the tip. The bypass conduit is directly connectable to a suction source so that aspirated debris passes through the tip to the suction source. The suction tube thus prevents aspirated debris from entering the conventional suction tube in the handpiece and contaminating the handpiece. The suction tube is also designed to have a maximum size to prevent the tip from clogging. The tip also has an irrigation tube for directing irrigation liquid to the irrigation site, and a connector which connects the irrigation tube to the handpiece so that the handpiece pumps fluid through the tip in a conventional manner. A flexible splash shield, slidably mounted to the irrigation tube, confines irrigation fluid to the local site.

  • Patent number: 6293928
    Abstract: A cannula for vaginal irrigations includes a straight cylindrical duct (1) whose proximal end is shaped to form a connection (4) for the mounting on a supplying device (5) containing a treating solution, as well as an ogive (2) extending rearwards from the distal end of said duct (1) so as to enclose externally the distal portion of the duct (1), whose distal end is in communication with the outside through a ring of at least four holes (3) formed on the tip of the ogive (2). The ogive (2) has an elliptical shape both in the longitudinal plane and in the plane orthogonal to the longitudinal axis and extends almost to mid-length of the duct (1), while the holes (3) are inclined at 30° with respect to the axis of the duct (1) both in the sagittal plane and in the longitudinal plane orthogonal thereto. The anatomical shape of the ogive (2) and the arrangement of the holes (3) provide an irrigation which is correct, effective and without risks for the user.

  • Patent number: 6179807
    Abstract: An irrigator (20) useful for surgical and medical procedures. The irrigator includes a handpiece (22) to which a tip assembly (30) is attached. The handpiece (22) includes a drain tube (50) that extends through the body of the handpiece and outside of the handpiece to the complementary suction system. The tip assembly includes a discharge tube (32) that is snap secured into the front of the handpiece and a suction tube (48) that seats in the open front end of the drain tube. A removable splash shield (181) is attached to the front end of the tip assembly. A trigger (44) allows one-handed control of, the position of the handpiece, the on/off state of the irrigator and the rate at which fluid is discharged from the irrigator. A rechargeable power pack (222) can be used to supply the energization current needed to activate a number of different handpieces at different speeds.

  • Patent number: 5928190
    Abstract: A duel system for flushing and vacuuming the sinuses comprising a main plate (1) having two voids (42 and 43) with collars (44 and 45) extending below. The voids hold two containers (25 and 26) with lids (9 and 10). Wing clips (2) attached to the main plate (1) holds adjuster plate (5) in recess (32) having mortise (33) within. Adjuster plate (5) accepts suction tube (39) and saline tube (40), with nose plugs (7E and 7F) on their ends. Wing clips (2) when rotated, allows adjuster plate (5) to be picked up and rotated, reversing tubes (39 and 40) and nose plugs (7E and 7F). Tubes (38, 39, 40 and 41) are secured in slots (27, 28, 29 and 30). Air compressor (24) creates pressure in pressure container (26) through pressure tube (41). The pressure pushes saline through saline tube (40) that passes up through lid (10), mortise (33), hole (6) in adjuster plate (5), and has nose plug (7F) on the end. Saline passes through nose plug (7F), up one nostril through the sinuses and down the other nostril.

  • Patent number: 5304116
    Abstract: An improved vaginal cleansing device comprising a T-shaped coupling, a first valve, a venturi, a second valve, concentrate reservoir, a solution delivery tube, and an applicator nozzle. The T-shaped coupling is interposed between a water source line and a shower head and diverts water to the first valve. The first valve controls the flow of water through the cleansing device and, when open, delivers water to the venturi. The venturi drafts concentrate from the concentrate reservoir under the control of the second valve and delivers either water or a mixture of water and concentrate to the solution delivery tube, and the solution delivery tube delivers the water or mixture to the applicator nozzle.

  • Patent number: 5300022
    Abstract: An improvement over the Foley catheter which provides, in addition to the main drainage lumen, a central smaller lumen for continuous delivery of a small quantity of sterile irrigating solution directly through the distal tip into the bladder. A larger portion of the irrigating solution is deflected by the cone shaped roof of the distal tip and turned backward past the drainage ports and into the drainage lumen. This backward flow of liquid causes a mild suction which assists the removal of clots and tissue debris from the bladder. The continuous flow of sterile solution also cleanses the drainage lumen and prevents the upward movement of bacteria common in most urinary catheters. A suction syringe can also be used in the usual manner in the event of a blockage. A second embodiment of the invention provides two protuberances across from the drainage ports within the distal tip to assist in breaking up clots as they enter the drainage lumen.
